This blog post discusses the insights from a webinar on sustainable surface coatings for fasteners in the construction industry, highlighting the importance of corrosion protection, evolving market standards, and innovative solutions to reduce carbon footprints.
In a recent webinar, experts Dr. Regina Martens and Pascal Gelino discussed the critical topic of sustainable surface coatings for fasteners in the construction industry. The session aimed to provide insights into the evolving needs for corrosion protection and the sustainable solutions available to meet these requirements.
Webinar Structure
The webinar was structured into two main parts: a 50-minute presentation followed by a 10-minute Q&A session. Participants were encouraged to engage by submitting questions throughout the presentation.
Overview of the Construction Industry's Needs
Market Changes
The construction industry is currently facing significant changes, particularly in technical requirements for surface coatings. The need for harmonized technical standards is pressing, as the existing requirements are still quite fragmented. New international standards, such as ISO 2702 and ISO 4042, are being developed to address these gaps, focusing on heat-treated tapping screws and electroplating coating systems, respectively.
Sustainability and Carbon Footprint
Sustainability has transitioned from a theoretical concept to a financial imperative. The carbon footprint, defined as the total CO2 emissions associated with an entity's activities, is under increasing scrutiny. The European Green Deal aims for a 55% reduction in greenhouse gas emissions by 2030, emphasizing the need for sustainable practices in all industries, including construction.
Technical Standards and Specifications
ISO 4042
The ISO 4042 standard for electroplating coating systems has been revised to prioritize its requirements over other documents. This standard includes critical information on preventing internal hydrogen embrittlement, which is vital for ensuring the integrity of fasteners used in construction.
Corrosion Resistance Testing
Two primary tests are used to evaluate corrosion resistance in fasteners: the Neutral Salt Spray Test (NSST) and the Castan Test. These tests help determine the longevity and durability of coatings under various environmental conditions.
Sustainable Coating Solutions
Electroplating and Zinc Flake Coatings
Both electroplating and zinc flake coatings offer excellent corrosion protection. Electroplating involves applying a zinc or zinc alloy layer, while zinc flake coatings provide a robust alternative with no hydrogen generation, thus minimizing the risk of embrittlement.
Innovations in Coating Processes
Recent innovations focus on reducing energy consumption and chemical waste during the coating process. For instance, the Uni Prep D35 WL system operates at lower temperatures, extending the solution's lifespan and reducing CO2 emissions by 15-40% during the cleaning phase.
Product Portfolio Overview
Base and Top Coats
The webinar highlighted various products, including single-layer base coats that can achieve high corrosion resistance with reduced operational costs. For example, the TNC 200 SLF base coat can provide up to 360 hours of corrosion resistance with integrated lubrication properties.
Zinc Nickel Coatings
Zinc nickel coatings offer superior corrosion resistance compared to traditional zinc coatings. They significantly reduce the risk of hydrogen embrittlement and provide a more durable finish, making them ideal for high-performance applications in construction.
